【摘要】 采用有限元法分析了棒材连续热轧中变形区及出变形区时轧件横断面温度场。变形区内热接触作用对轧件表面温度有较大影响， 温度梯度较大， 轧件出变形区后温度梯度逐渐减小， 温度分布较均匀。这一结果可指导分析轧件的微观组织变化。更多还原

【Abstract】 The temperature field of the bar in and out the deformation zone during continuous rolling is simulate by finite element method. It has been found that the temperature gradient is great in the deformation, on which the heat conduction has great effects and the temperature gradient is small out the deformation. The results are important to analyses the microstructure of the rolled-piece.更多还原
